PATENT FFlCEw TRACK-SANDER.

SPECIFICATION forming part of Letters Patent No. 745,065, dated.November 24, 1903.

Application filed June 10, 1903. Serial No. 160,795. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES E. M. KNIGHT, a citizen of the UnitedStates, residing at Huntington, in the county of Huntington, State ofIndiana, have invented certain new and useful Improvements inTrack-Sanders; and I do hereby declare the following to bea full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to sanding devices for cars; and it has for itsobject to provide a pneumatically-operated means for feeding the sandfrom the sand-box to the rail, a further object of the invention beingto provide aconstruction which may be adjusted to secure the bestresults under different specific.

conditions and in which the feedof the sand may he graduated.

An additional object of the invention is to provide a construction fromwhich any obstructions may be removed readily and without disjointingthe several parts of the appaent invention.

through the head or casing of the sander.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in both of the views,Figure 1 is a side elevation showing a sanding apparatus embodying thepres Fig.1) is a vertical section Referring now to the drawings, thepresent sander comprises a sand-box 5, from which leadswhat may betermed a suction-pipe 6, which extends downwardly and through which sandfrom the sand-box is drawn for discharge to the track. Engaged with thelower end of the suction-pipe is a head or casing 7, having the verticaltubular branches 8 and 9, which aline, and the horizontallyaliningtubular branches 10 and 11, the suction-pipe having threaded engagementin the upper branch 8 of the casing. Within the branch 10 of the casingis screwed a bushing '12, and into the inner end of the bushing andlying within the casing and in axial alinenientrwith the branches 10 and11 of the easing is a nozzle 13, having a head 14 at its free end, whichlies just short of the inner end of the branch 11 of the casing and withits face in close relation to the inner end of the bushing 14, which isscrewed into the branch 11 of the casing. The outer end of the bushing14 is threaded to receive the discharge-pipe or delivery-pipe 15,through which the sand from the casing is blown to the track to besanded, said pipe extending outwardly or horizontally and thendownwardly and rearwardly, so that it may lie with its discharge endclose to the surface of the rail to be sanded and just in advance of acar-wheel.

The inner end of the bushing 14: is gradually increased in internaldiameter from the point of engagement of the discharge-pipe to 55 theinnerend of the bushing, so that the sand may flow unobstructedly fromthe casing to the bushing.

The lower branch 9 of the casing 7 is internally threaded to receive aplug 10, which is bushing 14, so that by suction in the pipe (3 and thecasing '7, the sand is drawn from the sand-box into the casing and thenblown out through the bushing 1% into the deliverypipe 15, through whichit is forced and discharged onto the ,track.

the casing in great part by its own weight; but the suction establishedinsures an oven feed of sand.

It will be under- 35 stood, of course, that the sand will fall into Bythe use-of the bushings described -and go the arrangement of theair-discharge nozzle the ditferentparts of the apparatus may be readilyadjusted to obtain a greater or lesser discharge of sand, itbeing'understood theatr in practice modifications of the specific constructionshown may be made and that any suitable materials and proportions maybeused for the various parts without departing from the spiritof theinvention.

What is claimed is-- In a sanding apparatus, the combination with acasing having vertically-alining tubular branches andhorizontally-alining tubular branches, of a sand-box having asuction-pipe depending therefrom and engaged in the upaway frem theinner edge of the said bushper vertical branch of the casing a bushinging to vary the sand-supply,fand a plug re in one of the horizontalbranches of the. movably engaged in the'lowe'r vertical branch easing,and an airsupply pipe connected of the casing? 4 I e, 5 with theeppositehorizontal branch, a nozzle In testimony whereof I affix my'sign'abureI5 within the casing'connected adjustably'wibh in presence of twowibnesses.-
